I have an ejector pit that will sometimes kick on every 10 minutes. This seems to happen after a strong storm, although not always. The only things draining into the pit are the A/C, the utility sink, and the washer. After observing the pit more closely, I have noticed that even after it kicks on, I hear water draining/running? inside the pit? Not sure where this water is coming from, but it seems to cause the pump to run so frequently - 24/7! Of course, the washer and utility sink are not draining, and the A/C drains only slightly when this is happening. At times, the A/C is even off, so nothing is draining into the pit. Help.
